Law enforcement still assessing I-35 pile-up

The fallout continues after Monday's massive pileup on Interstate 35 in Ames.  Iowa State Patrol officials said they're buried in paperwork and still don't quite know the exact number of cars involved, though they estimate it was about 70.  One person died and nearly 20 others were hospitalized after the crash, which was caused in large part by the snowy weather.  Reports show several local and state agencies responded to the scene, including the Iowa Department of Transportation, Story County first responders, and the Story County Sheriff's's Office.
